DELL PowerEdge R640 1U rack server 2x Xeon Gold 6148 2.4GHz 20-core 768GB DDR4 8x 1.2TB SAS H730P

Dense 1U dual-socket platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out deployments. Two Xeon Gold 6148 processors deliver 40 cores at 2.4 GHz with 3.7 GHz turbo. 768 GB of DDR4 registered ECC memory fills all 24 slots. Eight 1.2 TB SAS drives connect through a PERC H730P controller supporting RAID 0, 1, 5, 6, 10, 50 and 60.

Suits virtualization farms, not GPU clusters

This configuration targets organizations running virtualization, container orchestration or memory-heavy databases that benefit from high core counts and large DRAM capacity in a single rack unit. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ links for flexible fabric integration. Buyers who require GPU acceleration or more than eight internal drive bays should consider larger chassis options.

768 GB DDR4 in 24 slots decides fit

The installed memory occupies every DIMM socket, leaving no room for expansion without removing modules. Maximum platform capacity reaches 3 TB, but achieving it requires replacing the current 32 GB sticks. Confirm that the fixed 768 GB baseline satisfies the working-set size of the intended workload before committing to this unit.
